Application May 7, 1945; Serlal No. 582,469

In my copending application Serial No. 466,961,

filed November 25, 1942, now Patent No. 2,381,550, I have shown a governor for an internal combustion engine which utilizes the intake'passageway suction, as modified by an air bleed to atmosphere which is controlled by an engine driven centrifugally unbalanced valve, for actuating the throttle valve to govern the engine speed. The centrifugal air bleed valve in my engine governor controls the flow of atmospheric air through the air bleed orifice into the engine intake manifold.

I accomplish the above set forth object by combining the centrifugal air bleed valve arrangement of my governor with the engine distributor housing so that the gas present in the ignition distributor housing is exhausted or bled into the engine intake passageway and I replace the gas withdrawn from the ignition distributor housing by fresh air which is preferably filtered,

This application is a continuation-in-part of my above specified patent. g

The drawing shows my ventilated ignition distributor in combination with my engine governor.

Since my engine governor is described and claimed in my above specified application, I will only briefly describe the governor per se. My

governor comprises the following parts: housing I, inlet 2, outlet\3 to the engine, throttle valve 4 controlling the flow of gas through intake passageway 5, suction device 6 connected into the intake passageway below the throttle by conduit I and above the throttle by conduit 8, tension spring 9 tending to hold the throttle open, diaphragm I0, conduit II connecting suction chamber I2 with passageway I3, valve housing I4, centrifugally unbalanced valve l5,-valve chamber l6, bypass I1, air bleed orifice I8, tension spring I8. Passageway I3 is in the engine driven distributor shaft 20. The above described governor is the same as that shown in my copending application and operates to control the speed of the engine.

Valve I closes momentarily whenthe engine reaches its governed speed to close air bleed oriflce I8 whereupon the intake passageway suction 4 Claims. (Cl. 123-103) I is established in chamber I2 causing diaphragm III to move throttle valve 4 toward closed position to throttle the charge flowing into the engine sothat the power developed by the engine will be suilicient to run the engine at its governed speed for whatever load is imposed upon the engine. If the load on the engine is increased,

then the speed oi! the engine will decrease slightly and valve I5 will move further open to air bleed o suction chamber I2 which will permit spring 8 to move valve 4 toward open position to increase the charge sufliciently to maintain the governed speed. I

In bleeding suction device l2, air flows through orifice I8, cylinder I6, passageways I1 and II.

conduits II and I into the intake passageway.

' This air or gas-is drawn from the air within distributor housing 2|. The air within distributor housing 2| will have whatever ozone is generated by the circuit breaker and distributor points.

The distributor is not shown in detail becausethe distributor can be any well-known or conventional distributor.

I have shown the distributor arm 22, the distributor points 23 and the wires 24 leading to the spark plugs. The distributor cap 25 is sealed tightly on the distributor housing 2| by seal 28. It is understood, of course, that the inside of cap 25 is in communication with the inside of housing 2|. Housing 2| is provided with an air inlet 21 providedwith an air cleaner 28. To prevent any air leakage into, housing 2|, except through port 21, shaft 20 is provided with gaskets or seals at III and 3|. Thus, while the engine is opa crating, valve I5 rides the vacuum, so to speak,

than that of conduits I, 8 and II and orifice B is smaller than oriflce'A. This improves the operation of the governor. a

I claim: I v

1. In an internal combustion engine having an sageway, a suction responsive device for controlling' said throttle valve, a conduit connecting the suction device into the intake passageway on the engine side or the throttle valve, an ignition diatributor including a housing therefona conduit intake passageway, a throttle valve in said pas connecting said housing with the suction device and the aforementioned conduit, centrifugal valve mechanism actuated in accordance with the speed of the engine and located in said distributor housing for controlling the flow of gas from .the housing through said conduits into the intake passageway to bleed the vacuum in said suction device whereby said suction device controls the throttle valve in accordance with the charge required by the engine to maintain its governed speed, and an air inlet into said distributor housing through which fresh air flows as the gas including ozone created in the distributor housing is exhausted from within the distributor housing.

2. In an internal combustion engine having an intake passageway, a throttle valve in said passageway, a suction responsive device for controlling said throttle valve, a conduit connecting the suction device into the intake passageway on the engine side of the throttle valve, an

air bleed for said suction device and said conduit including a centrifugal valve mechanism actuated in accordance with the speed of the engine for controlling the bleeding of airto said suction device and conduit, an ignition distributor including a housing, said air bleed and centrifugal valve mechanism being sealed within the said distributor housing whereby the said air bleed mechanism controls the exhausting or air and ozone created in the ignition distributor housing from said housing. I

3. The combination as set forth in claim 2 including an air inlet into said ignition distributor housing and an air cleaner for said air inlet whereby as-the air and ozone are withdrawn from the ignition housing fresh air flows into the housing through said air inlet.

valve housing with said suction device and the.

aforementionedconduit, an orifice in said valve housing, a centrifugally unbalanced valve positioned within said housing for controlling the orifice, said valve tending to close momentarily as the engine reaches its governed speed whereby the suction device responds to intake passageway suction and tends to move the throttle valve towardclosed position in accordance with the charge required by the engine to maintain its governed speed, an air inlet into said distributor housing whereby air flows into the distributor housing as air and ozone created by the distributor is Wlthdl' awn from the distributor housing through said valve controlled orifice.-
